Overview

Open|SpeedShop at SC18

Members of the Open|SpeedShop team will be at Super Computing in 2018. This year we will, once again, have booth (2840) and will be giving demonstrations on-demand throughout the show at the Open|SpeedShop booth: 2840. We are presenting our new high level, lightweight performance overview tool that gathers performance information for a number of metrics including MPI, OpenMP, I/O, Memory, and hardware performance counters to give a high level view of application performance in one run.

To schedule a meeting with Jim or Don please send email to jeg AT krellinst.org or stop by the booth.

Members of our team are presenting the “How to Analyze the Performance of Parallel Codes 101” tutorial on Monday, 11/11/18 (8:30am-5:00pm). The SC18 tutorial slides are now available: Here is the URL.

Overview
Open|SpeedShop (O|SS) is an open source multi-platform performance tool enabling performance analysis of HPC applications running on both single node and large scale Intel, AMD, ARM, Intel Phi, Power PC, Power 8, GPU processor based systems, including Cray and IBM Blue Gene platforms.

O|SS is a community effort by The Krell Institute with current direct funding from DOE NNSA. Argo Navis Technologies, LLC, a for-profit company working with Krell, recently won a Phase II NASA SBIR to further develop O|SS. O|SS builds on top of a broad list of community infrastructures, most notably Dyninst and MRNet from UW, libmonitor from Rice, and PAPI from UTK.

Open|SpeedShop development is hosted by the Krell Institute. The infrastructure and base components of Open|SpeedShop are released as open source code primarily under LGPL.

Highlights

No need to recompile the user’s application to get performance data at the function and library level. The debug option “-g” is needed in order to view statement, loop, and vector instruction level information.

Option to automatically group like performing processes, threads, or ranks.

Open|SpeedShop at SC17

Members of the Open|SpeedShop team will be at Super Computing in 2017. This year we will, once again, have booth (833) and will be giving demonstrations on-demand throughout the show at the Open|SpeedShop booth: 833.

To schedule a meeting with Jim or Don please send email to jeg AT krellinst.org or stop by the booth.

Members of our team are presenting the “How to Analyze the Performance of Parallel Codes 101” tutorial on Monday, 11/13/17 (8:30am-5:00pm). The SC17 tutorial slides are now available: Here is the URL.

In this article, we will describe how to use Open|SpeedShop through step-by-step examples illustrating how to find a number of different performance bottlenecks. Additionally, we will describe the tool’s most common usage model (workflow) and provide several performance data viewing options.

The Open|SpeedShop release tarballs will be moving to github in the future. The release tarballs are currently still being hosted on sourceforge.

Open|SpeedShop at SC16

Members of the Open|SpeedShop team will be at Super Computing in 2016. This year we will, once again, have booth (1442) and will be giving demonstrations on-demand throughout the show at the Open|SpeedShop booth: .
